Building a capture the flag challenge

paul78

I was wondering if anyone has any experience with building or implementing a capture-the-flag (ctf) challenge environment for training security professionals?

I'm looking for something that could give me a head-start in building something in a contest setting.

I'm aware and familiar with the usual kits out there like Metasploitable, WebGoat, DVWA, VulnerableByDesign, and the various OWASP demo projects. etc.

I was wondering if people have just stitched together their own from these systems or if there is different or better method to creating a CTF challenge.

Any ideas/thoughts appreciated.

locally if give them netbooks with a clean install of kali and an hour to config/install as they want

over the internet ya cant really control that much
